我们报告了约翰逊噪声测温在693 K到800 K范围内的新结果。该结果是基于一个量化电压噪声源（QVNS）的操作，作为相对噪声功率谱密度的参考。本文描述了对系统的修改，以克服我们以前工作中的局限性，并进一步使T-T90在更高温度下的测量成为可能。
We report new results for Johnson noise thermometry in the range 693 K to 800 K. The results are based on operation of a quantized voltage noise source (QVNS) which serves as a reference for the relative noise power spectral density. This paper describes the modifications to the system in order to overcome the limitations in our previous work and furthermore enable measurements of T-T90 at higher temperatures.
